How Do I Encrypt Transcoded Videos Using HLS? What Is a Key URL? How Do I Obtain It? What If the URL Validation Expires? Can Audio Files Be Encrypted During HLS Encryption? What Are the Differences Between HLS Encryption and Hotlink Protection?
Why Does the Encrypted HLS URL in the Original Streaming URL Remain Unchanged After the Encrypted HLS URL Is Changed? If the URL for obtaining the key is changed, you need to re-encrypt the video. Otherwise, the new encryption key does not take effect. Parent topic: Security
Can Encrypted Videos Be Played After the URL for Obtaining Keys Is Changed? If the original URL for obtaining the key is still valid, the encrypted video can still be played. If the original URL for obtaining the key is no longer used, configure a new URL on the console and transcode
Table 5 TransTemplateRsp Parameter Type Description group_id String Template group ID. name String Template group name. is_default Boolean Whether to use the default transcoding template. type String Template group type. is_auto_encrypt Boolean Whether to encrypt the output audio/
NOTE: If both template_group_name and workflow_name are specified, template_group_name takes effect. auto_encrypt No Integer Whether to automatically encrypt a file Possible values are: 0: not encrypted 1: encrypted Default value: 0 A file must be encrypted and transcoded at the same
Default value: 5 Encryption Whether to encrypt output media files. Input audio/video files are not encrypted. This parameter is available only when Output Format is set to HLS. That is, only HLS audio/video files can be encrypted and output.
After the configuration is complete, you need to use the transcoding function to encrypt video files. HLS encryption must be enabled for the transcoding template. Parent topic: Security Settings
(Optional) Configuring Global Settings If you need to transcode, watermark, and encrypt media files or receive notifications, configure related settings before uploading these files to VOD and then select a template to process these files during or after upload.
Why Does the Encrypted HLS Video Playback Failed? Possible causes are as follows: The decryption key cannot be obtained. The possible cause is that the URL for obtaining the key is incorrect. You can press F12 when previewing an encrypted HLS video on the console to check whether

How Do I Encrypt Transcoded Videos Using HLS? HLS encryption is performed during transcoding. To encrypt transcoded videos using HLS, you need to transcode the videos again and enable Encryption in the transcoding template. For details, see Transcoding Settings.
Can Audio Files Be Encrypted During HLS Encryption? Yes. However, you need to transcode the audio files to the HLS format. Configure a transcoding template as highlighted in Figure 1. Figure 1 HLS transcoding template Before transcoding, you need to set up the key management service
Why Can't an Encrypted HLS Video Be Played After Being Transcoded for the Second Time? The possible cause is that the key cache is configured on the encrypted HLS server. The Key Management Service (KMS) can cache the queried key locally. When another playback device requests the
If the value is not specified, the default value is used. is_auto_encrypt No Boolean Whether to encrypt the output audio/video. The default value is false (not encrypted). Only HLS audio/video streams can be encrypted before being output.
NOTE: If both template_group_name and workflow_name are specified, template_group_name takes effect. auto_encrypt No Integer Whether to automatically encrypt a file Possible values are: 0: not encrypted 1: encrypted Default value: 0 If encryption is required, a transcoding template
If the value is not specified, the default value is used. is_auto_encrypt No Boolean Whether to encrypt the output audio/video. The default value is false (not encrypted). Only HLS audio/video streams can be encrypted before being output.
For details, see Transcoding Settings in VOD User Guide. auto_encrypt No Integer Whether to automatically encrypt a file Possible values are: 0: not encrypted 1: encrypted Default value: 0 A file must be encrypted and transcoded at the same time.
